Procrastinate on all my projects.
Buy more keyboard parts that I never use.
Maybe tinker with a keyboard design I have, but never finish it.
Get super-focused on coding over-engineered firmware for a couple of weeks, doing nothing else, and then leave it.
That... sounds a lot like my likely list. If you make the nouns more general, you described most of my nonprofessional life.
Actually, though, the last couple years have been about trying to stop that, with a little success. This year, I'm massively paring down the number of weird, random **** I play with to focus on design and metalwork. I bought a milling machine; a lot of it is being delivered tomorrow, the rest on Monday. With a little luck and assuming I manage to avoid doing something stupid, I should be able to cut in the comfort of my own home in a month or so. So hopefully I'll improve faster than I have been, only getting shop-time about once a month. (Although I'll still depend on the shop a lot - no lathe, bandsaw, buffer, grinder, etc., and there are hard limits on size, type and power consumption of equipment one can reasonably house in a second-floor urban apartment.)
So my keyboard goal for the year: make my own, including the PCB and some firmware modifications. I know I can cut the case, and coding is no problem. (Famous last words - I haven't done much embedded, but from what I've seen, this looks reasonable enough.) It will be my first PCB, so that's the portion offering me a serious learning curve and is the most likely candidate for not happening. We'll see.
Since I'm congenitally incapable of working on one thing at once, I have a few smaller things in mind as well, but they're still, if you squint, computer peripherals.
I'm mostly posting this so I can point and laugh at myself in a year.
